AGREEMENT STATE REPORT - LOST SOURCE

The following was received from the Massachusetts Radiation Control Program (the Agency) via email:

"The licensee (QSA Global, Inc., License No. 12-8361) reported at 1400 [EST], on February 23, 2021 that it discovered on same day (February 23, 2021) at 1200 [EST], that a package (Yellow-III, T.I. 1.5, Type B, UN 2916) containing one sealed source (Co-60, 62.6 Ci, SN 88647G) in a Sentry radiographic exposure device (SN P01017) was missing.

"The package was shipped by QSA Global, Inc. on January 29, 2021 for export to their customer Acuren Group, based in Canada. On February 23, 2021 at 1200 [EST], Acuren Group reported to QSA Global, Inc. that the package was not received. On February 23, 2021 at 1400 [EST], QSA Global, Inc. reported the event to the Massachusetts Radiation Control Program.

"The [common] carrier indicated that the package was at their Memphis facility on January 31, and that since then the location is unknown.

"The reporting requirement is immediate and is of 105 CMR 120.281(A)(1), missing licensed radioactive materials in aggregate quantity equal to or greater than 1,000 times quantity specified in 105 CMR 120.297, Appendix C. The four-hour reporting requirement of 105 CMR 120.077(B), missing shipment of Category 2 quantity of radioactive material, also applies.

"The Agency considers this event to be open."

THIS MATERIAL EVENT CONTAINS A "CATEGORY 2" LEVEL OF RADIOACTIVE MATERIAL

Category 2 sources, if not safely managed or securely protected, could cause permanent injury to a person who handled them, or were otherwise in contact with them, for a short time (minutes to hours). It could possibly be fatal to be close to this amount of unshielded radioactive material for a period of hours to days. These sources are typically used in practices such as industrial gamma radiography, high dose rate brachytherapy and medium dose rate brachytherapy.

SAFETY LIMIT EXCEEDED

Based on video surveillance and radiation readings, National Institute of Standards and Technology (NIST) has determined they violated Safety Limit 2.1 - greater than 450 degrees Celsius in a single fuel element. This event notification relates to Event Notification #55094, from 2/3/21.
